| 摘 要： | 针对连续SiC纤维增强钛基复合材料(SiC_f/Ti)成形的技术难题,利用沿垂直纤维方向基体具有大变形的能力,可以采用超塑成形/扩散连接技术(SPF/DB)成形出复合材料空心构件。在不同工艺参数条件下,测试了SiC_f/Ti复合材料的横向高温变形规律,并分析了变形温度、应变速率、纤维含量等工艺参数的影响规律,对不同参数条件下拉伸试件的微观组织和断口形貌进行了对比,分析了复合材料的高温变形机制。

| Abstract: | In order to resolve the technical problems of continuous SiC fiber reinforced titanium matrix composites (SiCf/Ti) formation, the large strain deformation ability of SiCf/Ti in the direction perpendicular to the fiber was used, and the superplastic forming/diffusion bonding(SPF/DB) process was introduced into the fabrication of SiCf/Ti composites. The deforming behavior of SiCf/Ti at high temperature of different process parameters were studied in detail. The influence of temperature, strain rate, fiber volume on the deformation were analyzed, the deformation mechanisms of SiCf/Ti composite at high temperature were discussed. |
